I think Jared Goff has turned out to be the perfect QB to rebuild a team with. He has his limitations, but he will very seldom lose you a game. If you put pieces around him, he will succeed and you will win games.
Might he be the QB you go all the way and win a Super Bowl with? Not if you ask the Rams. That doesn't mean you can't win in the interim though, even long-term, while waiting to catch lightning in a bottle with a Mahomes, Allen, or Rodgers in a spot where you can take them, place them in a position to succeed, and not have to completely mortgage any future chance at success.
You don't have to force the issue with drafting a QB you aren't in love with the way the Jets, Texans, and Panthers may need to do right now.
